Cryogenics
Abstract: Cryogenic treatment is process done after conventional heat treatment process in material processing technology.It is a permanent treatment done only once which affects the whole section of the component. It is not acoatings of superior materials over other metal surfaces that only affects the surface of components. Cryogenic treatments are proved to be a good way to decrease the retained austenite content and improve the performance of materials by improving …

Solar Assisted Dehumidification System Using Liquid Desiccant (Design)
Abstract: Approximately one-third of the food produced (about 1.3 billion ton), worth about US $1 trillion, is lost globally during postharvest operations every year. India, being agricultural dominated country, large amount of agricultural products is cultivated each year, but due to lack of proper storage facilities considerable amount of agricultural products like grains, onions, potatoes gets spoiled /rote due to atmospheric moisture. India has incurred post harvest losses to the tune …

Design, Calculation and Cost Estimation of HVAC system for School Building
Abstract: In this project work we are going to design the energy efficient HVAC system for a school building. The use of air conditioning systems for residential/office buildings were very minimum in the earlier days of 1980’s. Due to the technology advancement and industrial growth buildings were started construction in a closed area and construction of apartment also increased after 1980’s with increased population. Also, ambient temperatures are changed drastically due …

Indoor Room Air Conditioning Using External Enclosure
Abstract: This paper presents a new air conditioning system using an external air chamber enclosure. The system is based on evaporative refrigeration technique humidifying hot air from the environment by means of a new design humidifier. Temperature at the air chamber is set up according to the required comfort conditions. The air chamber plays the role of a heat collector from indoor room radiative energy. This new system avoids thermal gradient …
